* Add tests for polling for multiple messages
This commit adds a mock Redis interface and adds tests that poll the
mock interface for multiple messages at a time. These tests test that
Flodgatt is robust against receiving incomplete messages, including if
the message break results in receiving invalid UTF8.
* Remove temporary files
* Initial [WIP] implementation
This initial implementation works to send messages but does not yet
handle unsubscribing properly.
* Implement UnboundedSender
* Implement UnboundedChannels for concurrency
